The Navy’s much-hyped electromagnetic railgun has come a long way. Ever since the futuristic cannon enjoyed a public debut at the Naval Surface Warfare Center, Dahlgren Division in Virginia in November 2016, the Office of Naval Research has been working diligently alongside defense contractors to bring the decade-long program closer to battlefield effectiveness. Based on new video published by the Department of Defense, the railgun has successfully moved from single-shot to repeated firing rate operations — a major stepping stone on the path to the battlefield.
The ONR video shows the railgun conducting its first multi-shot salvos powered by repeated pulses in energy over a short period with minimal cooldown time, a critical system for efficient applications downrage. While the prototype unveiled in November can currently launch single high-density projectiles at velocities reaching Mach 6, or 4,500 mph, the Navy clearly wants more rapid firepower. The original request for information published by Naval Sea Systems Command in 2013 called for prototypes that could fire 10 shells a minute and store up to 650 shells; this is a weapon designed with repeat fire in mind.
Engineering a power source that can provide that fire — by repeatedly generating fluctuating electromagnetic fields over short periods of time — has been a priority for ONR. In June,Electromagnetic Railgun Program chief Tom Boucher told National Defense magazine that contractors BAE and General Atomics were testing new barrel designs and devastating pulsed-power systems capable of firing five shells in a single missile, raising the cannon’s rate of fire and increasing its destructive potential.
The newly released footage reveals that the program has met its goal — sort of. The railgun manages to build to full power and send a projectile down Dahlgren’s 25-mile Potomac River test range twice in 25 seconds, a firing rate of 4.8 shells a minute — just under the goal Boucher laid out in June. It’s mightily impressive, regardless, especially given the Navy’s intent to equip guided-missile destroyers and cruisers with the railguns — if only for defensive purposes.
Benjamin Franklin nailed it when he said, "Fatigue is the best pillow." True story, Benny. There's nothing like pushing your body so far past exhaustion that you'd willingly, even longingly, take a nap on a concrete slab.

Radio transmissions to the U.S. Coast Guard are usually calls for help from boaters, but one captain got on the radio recently just to say thanks to the men and women who are currently working without pay.
DOVER AIR FORCE BASE, Del (Reuters) - U.S. President Donald Trump traveled to Dover Air Force Base in Delaware on Saturday to receive the remains of four Americans killed in a suicide bombing in northern Syria.
Trump, locked in a battle with congressional Democrats that has led to a nearly month-long partial government shutdown, announced his trip via a pre-dawn tweet, saying he was going "to be with the families of 4 very special people who lost their lives in service to our Country!"
Former President George W. Bush is calling for an end to the partial government shutdown, which is about to hit the one-month mark and is currently the longest shutdown in US history.
In an appeal made on Instagram, the 43rd president called on "leaders on both sides to put politics aside, come together, and end this shutdown." The caption was posted with an image of him and former First Lady Laura Bush giving pizza to their Secret Service detail.
